JOHN S. HULL, OF BALTIMORE, MARYLAND.

TINNE'RS FIRE-POT.

SPECIFICATION forming part of Letters Patent No. 409,358, dated August 20', 1889.

Application filed March 22, 1889. Serial No. 304,252. (NomodeL) T0 aZZ whom it may concern.-

Be it known that I, JOHN S. HULL, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Tinners Fire-Pots; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to tinners fire-pots, and has for its object an improved construction of such devices which will prevent the point of a soldering-iron from being blunted or otherwise injured when thrust into the fire-pot.

In the practical use of tinners cast-iron fire-pots a serious difficulty has been encountered, in that by the careless handling of the soldering-irons, due to the haste and speed of the workmen, they are frequently thrust into the fire-pot with such violence as to cause the point of the iron to strike againstthe wall of the pot and blunt the iron to such an extent as to destroy its utility and require immediate repointing or dressing before it can be used to solder a joint. This defect. in the soldering-iron is not discovered until the seam to be soldered has been prepared and the iron properly heated, when, to the disgust and annoyance of the workman, he discovers that the iron, after having been heated and withdrawn from the fire-pot, is absolutely unfit for use. This defect in the iron results in loss of time and waste of heat and material. It is my purpose to obviate this difficulty by providing a'protecting medium for the point of soldering-irons, which shall be attached to the fire-pot.

The invention will be hereinafter described, and particularly pointed out in the claims.

In the accompanying drawings, which form a part of this specification, Figure 1 represents a plan view, and Fig. 2 a vertical section on the line on as, Fig. 1.

Reference being had to the drawings and the letters thereon, A indicates a firepot, provided with an opening B to receive a retorttube of a burner, a chimney O, and an opening D for the insertion of a soldering-iron E, (shown in dotted lines in Fig. 2,) all of which are of ordinary construction shown in my prior patents. On the rear side of the the pot is formed an extension F, in the upper side of which is a slot G, to receive a slab II, of soapstone, asbestus, or other non-combustible material of a nature that will not injure a soldering-iron should it strike against it. The slab H fills the cross-sectional area of the extension and forms an effective lining for the end of the extension and prevents loss of heat by radiation.

I indicates a bar crossing the fire-pot, upon which the soldering-iron rests and by which it is guided or directed and kept in line, so that the end of the line will always strike against the slab H, and the weight of the iron is supported by the bar while being heated.

I do not confine my invention to any spe cific means for securing the slab II, as it may be placed in the extension F from the inside of the firepot, thus dispensing with the slot G. In the construction shown the slab H is guided to its seat in the extension F and secured against displacement by ribs a, (only one of which is shown in Fig. 2,) which are cast integral with the fire-pot, and forms a shield or guard against which the solderingiron may be thrust without injury to its point. The shield may be removed as circumstances require.

Having thus fully described my invention, what I claim is 1. A tinners fire-pot having a bearing-bar to support and direct a soldering-iron, in combination with a slab or body of non-combustible material constructed to prevent the point of the soldering-iron from penetrating the slab and being projected against the metallic surface of the pot, substantially as described.

2. A tinners fire-pot having a bearing-bar to support and direct a solderingiron, and provided with an extension on its rear side, in combination with a slab of soapstone or its described equivalent constructed to prevent the point of the soldering-iron from penetrating the slab and being projected able through said slot, substantially as deagainst the metallic surface of the pot, substantially as described.

3. A tinners fire-pot provided With a bar or support I and an extension F, having a slot in the upper side thereof, in combination with a shield C, insertible and remov- In testimony whereof I affixniysignature in presence of two witnesses.

JOHN S. HULL.
